I am not sure I understand this question. The "model" IS a mesh, it's
a surface triangulation. You can save it into .vtk or .stl format.

I am not sure what you mean by "meshable surface". Do you want to
build a volumetric tesselation? Slicer has IA-FEMesh module that may
help you to construct a hexahedral mesh of this surface, or you can
use some external tool for tetrahedral tesselation.
